Matthew, I too have an Atomic 4. Fortunately, it hasn't given me that kind of trouble? How many hours on the motor? If there are a lot of hours, given that the oil pressure gauge fluxuates, you might have a blown head gasket or a cracked engine casing. This would allow oil into the chambers, foul the mixture, and cause the engine to lose compression. If you can get a compression gauge and check each cylinder, you might find the pressure in one or more pistons is not up to specs (don't have the specs on me right now). It could be any number of issues but it does sound like oil is making it into the cylinders, then out your exhaust system, hence the soot on the transom! My 2 cents worth! Wade
